Matters needing attention:
This power amplifier board is sold without heat dissipation fins. Before testing the power amplifier board, it is necessary to add sufficient heat dissipation fins (7809 regulated IC does not require heat dissipation fins). R8 and R10 are magnification settings for resistors (default for shipping is around 2-3 times magnification, and the magnification can be changed according to your own needs. Resistors can be selected from 10k-47k, and the larger the resistance value, the higher the magnification. If using plug-in resistors, you can remove the original chip resistors and place them on the solder pads at both ends of the plug-in)
